本申请主张2020年12月30日在中国提交的中国专利申请号202011631569.X的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种射频系统、一种射频系统的供电控制方法以及一种电子设备。
背景技术
随着通信技术的发展，第五代移动通信技术(5th generation mobile networks，5G)逐渐开始普及。为了实现从第四代移动通信技术(4th generation mobile networks，4G)到5G平稳过渡及基站建设的成本考虑，当前的5G组网方式通常为非独立组网(Non-Standalone，NSA)。在NSA模式下，5G需要依托4G核心网进行信令连接，4G功率放大器(Power Amplifier，PA)和5G PA同时工作。而后续的5G技术的发展，将会逐步向独立组网(Standalone，SA)方式发展。在SA模式下，4G和5G分别独立工作，5G可以单独信令工作，不需要依托4G核心网的辅助，4G PA和5G PA分别独立工作。
相关技术中，为了实现不同的工作状态，4G PA和5G PA需要同时工作，或者，4G PA和5G PA需要分别独立工作，因此，在射频系统中，通常需要设置两个PA电源芯片，其中一个与4G PA连接，用于控制4G PA的供电，另一个与5G PA连接，用于控制5G PA的供电。这样，不仅会增加射频系统的成本，而且，会增加射频系统在电子设备中的布局难度。
发明内容
本申请旨在提供一种射频系统、一种射频系统的供电控制方法以及一种电子设备，至少解决射频系统的成本高，在电子设备中的布局难度大的问题之一。
第一方面，本申请实施例提出了一种射频系统，包括：电源、PA电源芯片、PA模块、开关模块以及控制模块；
其中，电源通过开关模块与PA模块连接，PA电源芯片通过开关模块与PA模块连接，PA模块包括至少两个PA模组；
控制模块与开关模块连接，控制模块用于，根据射频系统的工作状态，控制开关模块的通断状态，以使电源和/或PA电源芯片为PA模块供电。
第二方面，本申请实施例提出了一种射频系统的供电控制方法，用于第一方面提出的射频系统，该方法包括：
获取射频系统的工作状态；
根据工作状态，控制开关模块的通断状态，以使电源和/或PA电源芯片为PA模块供电，其中，PA模块包括至少两个PA模组。
第三方面，本申请实施例还提供了一种电子设备，包括：上述任一项的射频系统。
本申请实施例中，电源通过开关模块与PA模块连接，PA电源芯片通过开关模块与PA模块连接；控制模块与开关模块连接，控制模块用于，根据射频系统的工作状态，控制开关模块的通断状态，以使电源和/或PA电源芯片为PA模块供电，以满足不同工作状态下PA模块的供电需求。也即，射频系统中，仅需一个PA电源芯片，配合开关模块的使用，即可实现满足不同工作状态PA模块的供电需求。这样，不仅会降低射频系统的成本，而且，还会降低射频系统在电子设备中的布局难度。

具体实施方式
下面将详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本发明的描述中，除非另有说明， “多个”的含义是两个或两个以上。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
图1示出了根据相关技术的一种射频系统的结构示意图，如图1所示，现有的射频系统具体可以包括：电源10，第一PA电源芯片100、第二PA电源芯片200、第一PA模组12以及第二PA模组13；其中，第一PA电源芯片100与第一开PA模组12连接，以对第一PA模组12进行供电，第二电源芯片200与第二PA模组13连接，以对第二PA模组13进行供电。
示例性地，第一PA模组12可以为4G PA模组，第二PA模组13可以为5G PA模组。在实际应用中，在NSA模式下，4G PA和5G PA同时工作。此时，第一PA电源芯片100可以为第一PA模组12供电，同时，第二PA电源芯片200可以为第二PA模组13供电。在SA模式下，4G PA和5G PA分别独立工作。此时，第一PA电源芯片100独立为第一PA模组12供电，第二PA电源芯片200独立为第二PA模组13供电。
在根据相关技术的射频系统中，由于需要采用两个PA电源芯片来进行PA的供电控制，且PA电源芯片的体积较大，成本较高，因此，整个射频系统的成本较高，布局难度较大。而且，没有充分利用电源10上预留的供电接口，电源10的利用率较低。
参照图2，示出了本申请提供的射频系统的实施例的结构框图，如图2所示，射频系统具体可以包括：电源10、PA电源芯片11、PA模块20、开关模块14以及控制模块15；其中，
电源10通过开关模块14与PA模块20连接，PA电源芯片11通过开关模块14与PA模块20连接，PA模块包括至少两个PA模组；
控制模块15与开关模块14连接，控制模块15可以用于，根据射频系统的工作状态，控制开关模块14的通断状态，以使电源10和/或PA电源芯片11为PA模块20供电。
本申请实施例中，电源10可以为电池，也可以为平台电源管理芯片 (Power Management IC，PMIC)，例如，MTK平台MT6359等，本申请实施例仅以电源10为PMIC为例进行说明，其他类型的电源参照执行即可。
具体地，PA电源芯片11可以为PA的专用电源供电芯片，能支持包络跟踪等供电技术，相比PMIC更省电，如高通平台QET5100/QET6100，MTK平台MT6308等，可以实现电源包络跟踪技术等省功耗技术，性能较优，可以实现PA省功耗的目的。
具体地，PA模块20可以包括至少两个PA模组，PA模组具体可以包括4G PA模组、5G PA模组等。开关模块14具体可以为电子开关、场效应管等能够实现电路通断控制的开关器件。控制模块15可以为电子设备的中央处理器，也可以为用于控制射频系统的专用控制芯片，本申请实施例对此不做特殊限定。
在实际应用中，射频系统的工作状态可以包括NSA模式工作状态、SA模式工作状态等，本申请实施例对此不做限定。为了适应不同的工作状态，控制模块15通过控制开关模块14的通断状态，控制电源10为PA模块20中的一个或者多个PA模组供电，或者，控制PA电源芯片11为PA模块20中的一个或者多个PA模组供电，或者，控制电源10为PA模块20中的一部分PA模组供电，并控制PA电源芯片11为PA模块中的另一部分的PA模组供电，本申请实施例对于具体地供电逻辑不做具体地限定。
本申请实施例中，由于电源10通过开关模块14与PA模块20连接，PA电源芯片11通过开关模块14与PA模块20连接；控制模块15与开关模块14连接，控制模块15可以用于，根据射频系统的工作状态，控制开关模块14的通断状态，以使电源10和/或PA电源芯片11为PA模块20供电，以满足不同工作状态下PA模块20的供电需求。也即，射频系统中，仅需一个PA电源芯片11，配合开关模块14的使用，即可实现满足不同工作状态PA模块20的供电需求。这样，不仅会降低射频系统的成本，而且，还会降低射频系统在电子设备中的布局难度。
在本申请的一些可选实施例中，工作状态可以包括：第一工作状态、第 二工作状态，以及第三工作状态，PA模块20可以包括第一PA模组12和第二PA模组13；其中，在射频系统处于第一工作状态下，控制模块15可以控制开关模块14导通PA电源芯片11与PA模块20的连接，以使PA电源芯片11为第一PA模组12供电，在射频系统处于第二工作状态下，控制模块15可以控制开关模块14导通PA电源芯片11与PA模块20的连接，以使PA电源芯片11为第二PA模组13供电，以使PA电源芯片11为第二PA模组13供电；在射频系统处于第三工作状态下，控制模块15可以控制开关模块14导通PA电源芯片11与PA模块20的连接，以及，导通电源10与PA模块20之间的连接，以使电源10为第一PA模组12和第二PA模组13的其中之一供电，PA电源芯片11为第一PA模组12和第二PA模组13中的其中另一供电。
具体地，第一工作状态可以为SA模式下，需要第一PA模组12独立工作的工作状态。第二工作状态可以为SA模式下，需要第二PA模组13独立工作的工作状态。第三工作状态可以为NSA模式下的工作状态。相应的，第一PA模组12可以为4G PA模组，第二PA模组13可以为5G PA模组；其中，第一PA模组12的数量可以为两个，一个第一PA模组12可以用于传输高频的4G信号，另一个第一PA模组12可以用于传输低频的4G信号。
具体地，在SA模式下，第一PA模组12和第二PA模组13无需同时工作，此时，在第一工作状态下，控制模块15可以控制开关模块14导通PA电源芯片11与PA模块20的连接，以使得PA电源芯片11可以为第一PA模组12供电；在第二工作状态下，控制模块15可以控制开关模块14导通PA电源芯片11与PA模块20的连接，以使得PA电源芯片11可以为第二PA模组13供电，实现电源包络跟踪技术等省功耗技术，达到较好的降功耗的效果。在第三工作状态下，第一PA模组12和第二PA模组需要同时工作，此时，控制模块15可以控制开关模块14导通PA电源芯片11与PA模块20的连接，以及，导通电源10与PA模块20之间的连接，以使电源10为第一PA模组12和第二PA模组13的其中之一供电，PA电源芯片 11为第一PA模组12和第二PA模组13中的其中另一供电，以通过一个PA电源芯片11，配合开关模块14的使用，即可实现满足不同工作状态PA模块的供电需求
参照图3-4，示出了本申请提供的射频系统的实施例的结构示意图，如图3、图4所示，开关模块14可以包括：第一开关模块141和第二开关模块142；第一开关模块141连接在电源10与第一PA模组12之间；第二开关模块142连接在PA电源芯片11与第一PA模组12之间。控制模块15分别与第一开关模块141、第二开关模块142连接，以控制第一开关模块141、第二开关模块142的通断状态。
如图3-4所示，射频系统中可以形成两个供电通道，其中，电源10、第一开关模块141以及第一PA模组12可以形成供电通道A，PA电源芯片11、第二开关模块142、第一PA模组12以及第二PA模组13可以形成供电通道B。在实际应用中，在第一开关模块141导通的情况下，供电通道A可以相应导通，在第二开关模块142导通的情况下，供电通道B可以相应导通。
如图3所示，在射频系统处于SA模式下，控制模块15可以控制第一开关模块141断开，第二开关模块142导通，供电通道A断开，供电通道B导通。此时，由于第一PA模组12和第二PA模组13无需同时工作。在需要第一PA模组12工作的第一工作状态下，PA电源芯片11可以按照图3中的供电路径b为第一PA模组12供电；在需要第二PA模组13工作的第二工作状态下，PA电源芯片11可以按照图3中的供电路径c为第二PA模组13供电。
如图4所示，在射频系统处于第三工作状态下，控制模块15可以控制第一开关模块141导通，第二开关模块142断开，供电通道A、供电通道B皆导通。此时，由于第一PA模组12和第二PA模组13需要同时工作，电源10可以按照图4中的供电路径a为第一PA模组12供电，PA电源芯片11可以按照图3中的供电路径c为第二PA模组13供电，以使得第一PA模组 12和第二PA模组13可以同时工作。
在本申请的一些可选实施例中，第一开关模块141为第一场效应管，第二开关模块142为第二场效应管；控制模块15上设有接口16，接口16分别与第一场效应管、第二场效应管连接，用于实现第一场效应管、第二场效应管的通断控制。进而，可以实现供电通道A、供电通道B的通断控制。
示例性地，接口16可以为通用输入/输出(General-purpose input/output，GPIO)接口，用于向第一场效应管、第二场效应管输出电平信号，控制第一场效应管、第二场效应管的通断。
具体地，第一场效应管的第一极与电源10连接，第一场效应管的第二极与第一PA模组12连接；第二场效应管的第一极与PA电源芯片11连接，第二场效应管的第二极与第一PA模组12连接；接口16分别与第一场效应管的栅极，以及，第二场效应管的栅极连接。
示例地，第一场效应管，第二场效应管可以为N型场效应管或者P型场效应管中的至少一种，本申请实施例仅以第一场效应管、第二场效应管皆为N型场效应管为例进行说明，其他场景参照执行即可。
在实际应用中，由于控制模块15上的接口16与第一场效应管的栅极连接，通过控制接口16向第一场效应管的栅极输出的电平信号，可以控制第一场效应管的第一极与第二极之间的通断状态。同理，由于控制模块15上的接口16与第一场效应管的栅极连接，通过控制接口16向第一场效应管的栅极输出的电平信号，可以控制第一场效应管的第一极与第二极之间的通断状态。
例如，在第一场效应管为N型场效应管的情况下，接口60向第一场效应管输出高电平信号时，可以控制第一场效应管的第一极和第二极之间导通，供电通道A导通；接口60向第一场效应管输出低电平信号时，可以控制第一场效应管的第一极和第二极之间不导通供电通道A不导通。
具体地，第一极可以为源极，第二极可以为漏级，或者，第一极为漏级，第二极为源极，本申请实施例对此不做限定。
可选地，接口16可以包括第一接口161和第二接口162；其中，第一接口161与第一场效应管的栅极连接，第二接口162与第二场效应管的栅极连接，以通过第一接口161控制第一场效应管的通断，通过第二接口162控制第二场效应管的通断。在实际应用中，通过独立的接口控制唯一对应的场效应管的通断，可以实现每个场效应管的独立控制，从而，可以提高控制精度。
示例地，在第一场效应管、第二场效应管皆为N型场效应管，在射频系统处于第一工作状态或者第二工作状态的情况下，第一接口161可以输出低电平信号，第二接口162可以输出高电平信号，第一场效应管不导通，第二场效应管导通；在射频系统处于所第三工作状态的情况下，第一接口161可以输出高电平信号，第二接口162可以输出低电平信号，第一场效应管导通，第二场效应管不导通。
参照图5-6，示出了本申请提供的射频系统的另一实施例的结构示意图，如图5、图6所示，射频系统还可以包括：反向器17；其中，反向器17连接在接口16与第二场效应管的栅极之间。反相器17可以用于对接口16输出的电平信号进行反向。
例如，在接口16输出的电平信号为低电平信号的情况下，经过反相器17反向后，输出为第二场效应管的电平信号为高电平信号；在接口16输出的电平信号为高电平信号的情况下，经过反相器17反向后，输出为第二场效应管的电平信号为低电平信号。
如图3至图6所示的射频系统中，无论射频系统处于第一工作状态、第二工作状态还是第二工作状态，第一场效应管、第二场效应管中仅有一个场效应管是导通的，也即，第一场效应管、第二场效应管输入的电平信号中，其中一个为低电平信号，另外一个为高电平信号，第一场效应管和第二场效应管输入的电平信号应该相反。
本申请实施例中，通过在接口16与第二场效应管之间设置反相器17，接口16向第一场效应管、第二效应管输出相同的电平信号时，在反相器17 的反向作用下，第一场效应管、第二场效应管输入的电平信号却可以相反。这样，通过一个接口16输出相同的电平信号，既可以实现两个场效应管的通断控制，减少接口的数量，而且，可以简化接口16的控制逻辑。
如图5所示，在第一场效应管、第二场效应管皆为N型场效应管，在射频系统处于第一工作状态或者第二工作状态的情况下，接口16可以输出低电平信号，第一场效应管输入的电平信号为低电平信号，由于反相器17的反向作用，第二场效应管输入的电平信号为高电平信号。
如图6所示，在第一场效应管、第二场效应管皆为N型场效应管，在射频系统处于第三工作状态的情况下，接口16可以输出高电平信号，第一场效应管输入的电平信号为高电平信号，由于反相器17的反向作用，第二场效应管输入的电平信号为低电平信号。
参照图7，示出了本申请提供的射频系统的再一实施例的结构示意图，如图7所示，电源10与第一PA模组12、第二PA模组13连接；PA电源芯片11分别与第一PA模组12、第二PA模组13连接。第三工作状态包括第三子工作状态和第四子工作状态。
在射频系统处于第一工作状态下，控制模块15可控制开关模块14导通PA电源芯片11与第一PA模组12的连接，以使PA电源芯片11为第一PA模组12供电，此时，第一PA模组12工作，第二PA模组13不工作。
在射频系统处于第二工作状态下，控制模块15可以控制开关模块14导通PA电源芯片11与第二PA模组13的连接，以使PA电源芯片11为第二PA模组13供电，此时，第二PA模组13工作，第一PA模组12不工作。
在射频系统处于第三子工作状态下，控制模块15可以控制开关模块14导通电源10与第二PA模组13的连接，以及，PA电源芯片11与第一PA模组12的连接，以使电源10为第二PA模组13供电，PA电源芯片11为第一PA模组12供电，此时，第一PA模组12、第二PA模组13皆工作，且PA电源芯片11为第一PA模组12供电的功耗较低。
在射频系统处于第四子工作状态下，控制模块15控制开关模块14导通 电源10与第一PA模组12的连接，以及，导通PA电源芯片11与第二PA模组13的连接，以使电源10为第一PA模组12供电，PA电源芯片11为第二PA模组13供电，此时，第一PA模组12、第二PA模组13皆工作，且PA电源芯片11为第二PA模组13供电的功耗较低。
需要说明的是，由于PA电源芯片11能支持包络跟踪等供电技术等省功耗技术，相比PMIC更省电，因此，在仅需要第一PA模组12或者第二PA模组13的情况下，可以控制PA电源芯片11为第一PA模组12或者第二PA模组供电，以降低射频系统的能耗。
示例性地，开关模块14可以包括如图7所示的第三开关模块143、第四开关模块144、第五开关模块145以及第六开关模块146；其中，第三开关模块143连接在电源10与第一PA模组12之间；第四开关模块144连接在电源10与第二PA模组13之间；第五开关模块145连接在PA电源芯片11与第一PA模组12之间；第六开关模块146连接在PA电源芯片11与第二PA模组13之间。
具体地，电源10、第三开关模块143以及第一PA模组12可以形成供电通道A1。电源10、第四开关模块144以及第二PA模组13可以形成供电通道A2。PA电源芯片11、第五开关模块145以及第一PA模组12可以形成供电通道B1。PA电源芯片11、第六开关模块146以及第二PA模组可以形成供电通道B2。
